What if they played it longer because they were interested in looking at the nose, to see how light affects it as you turn around? I for one would definitely do that.
Funny what all gets filtered out. When I'm wearing my extremely old plastic glasses (real ones, not VR), I do not perceive the myriad of scratches on it either, though it certainly contributes to less resolution of what I see, but I'm not aware. Most people are shocked when they get new glasses/lenses/eyes about the increase in detail they weren't aware of.
Which is not to say that you wouldn't have gotten used to and started ignoring a scratch you could see, because you're right; you would have. But that's not what's actually going on.
I'm going to guess that the person you're replying to is sufficiently familiar with his glasses to know what he actually sees.
